How to specify realm name when calling weak( ) method on ServletAuthentication class?
I've created a bunch of custom realms and for a specific user logon (form based "uname" and "pword"), the system knows exactly which custom realm to look up against. However, in using ServletAuthentication class, one can only specify realm name in strong(req, res, realmName), not the weak() method. Any clue?

Hi John,
Did you find the answer to this question? I'm having a similar problem when calling the ServletAuthentication.assertIdentity() method.
Cheers,

KSLD how to specify kernel name when run ksld command on host
I am trying to use KSLD v1.0 and I could not reproduce similar result shown on KSLD User Guide. I followed almost everything on KSLD User Guide except I don't know how to specify kernel name when running ksld command. Here is what I have tried.
#ksld -t debug /ksld-space/slo8/proto/root_sparc/platform/sun4u/kernel/sparcv9/unix 99
I can only get unix and krtld read in. (ksld_dbx)modules could not show any modules *.o
When I use this
#ksld -t debug /ksld-space/slo8/proto/root_sparc/platform/sun4u/kernel/sparcv9/genunix 99
then I can only read on genunix.
Example on KSLD User Guide use unix.281, what is unix.281 created or obtained from target.
I noticed some SUN Tachnical Support Guru are online to answer questions, thank you for your quick reply.I am having the same problem, did you get a solution?

Can't add list element when calling a method from another class
I am trying to call a method in another class, which contains code listmodel.addElement("text"); to add an element into a list component made in that class.
I've put in System.out.println("passed"); in the method just to make sure if the method was being called properly and it displays normally.
I can change variables in the other class by calling the method with no problem. The only thing I can't do is get listmodel.addElement("text"); to add a new element in the list component by doing it this way.
I've called that method within it's class and it added the element with no problem. Does Java have limitations about what kind of code it can run from other classes? And if that's the case I'd really like to know just why.There were no errors, just the element doesnt get added to the list by doing it this way
class showpanel extends JPanel implements ActionListener, MouseMotionListener {
framepanel fp = new framepanel();
--omitted--
public void actionPerformed(ActionEvent e){
if(e.getSource() == button1){
fp.addLayer();
/*is in a different class file*/
class framepanel extends JPanel implements ActionListener{
--omitted--
public void addLayer(){
listmodel.addElement("Layer"+numLayer);
numLayer++;

How to specify LPAR Name when connecting to AS400
Hi,
I am able to configure OS400 out of box adapter and able to do the reconcilation.
How ever we would like to fetch the As400 accounts from a PARTICULAR PARTITION.
Do we have this provision in OS400 out of box adapter?
Could you please provide any samples to specify the partition name in the url/in the fetching query.
Thank you,
ManiThe issuse was resolved.
Using the IP is equivalent to the LPAR name. So, it should not make any difference. -

Hello everyone,
Each time I used startWLS.sh (I installed weblogic8.1, and copied start script
from $home/weblogic81/server/bin/startWLS.sh to my new directory) to start the
server, the domain name is always "mydomain". How can I provide the domain names
by myself?
Thank you.

How to specify alias name in system property while making 2way SSL con ?
Hi All,
I am tring to run a java client with 2way SSL which uses CAC card as keystore for the client. I have addded the following system property in my client program to make it work and change the java.security file to add pcks11 provider.
System.setProperty("javax.net.ssl.keyStoreType", "pkcs11");
System.setProperty("javax.net.debug", "ssl");
The program works fine and handshake is successfully done . But the problem is when i have more than one trusted certificate in the CAC card, it take a default certificate. I want to specify the certificate that should be used to do the client auth maybe specify the alias name . I didnt find any system property to do so.
Please let me know how to specify alias name as system property so that the 2way SSL used the specified alias for the client auth or is there any other way to specify the alias name. As in case i acccess the server URL from any browser i get a certificate selection prompt and the connection is established with the selected certificate.
Thanks in advanced,
RuhulI didn't find any system property to do so.There isn't one.
Please let me know how to specify alias name as system propertyYou can't.
You would have to write a custom KeyManager. See the JSSE Reference Guide. -
I updated my iphone to iOS 6.0.1but it doesn't show the contacts names when calling or receiving calls. What to do?
This may be an error caused by the update. You can try to sync your contact information with iCloud and backup the rest of your data and then restore the device and see if it starts to work normally again.

How to create a session using call transaction method.
hi , this is nagaraju,
How to create a session using call transaction method.Hi,
About Data Transfer In R/3 System
When a company decides to implement the SAP R/3 to manage business-critical data, it usually does not start from a no-data situation. Normally, a SAP R/3 project comes into replace or complement existing application.
In the process of replacing current applications and transferring application data, two situations might occur:
The first is when application data to be replaced is transferred at once, and only once.
The second situation is to transfer data periodically from external systems to SAP and vice versa.
There is a period of time when information has to be transferred from existing application, to SAP R/3, and often this process will be repetitive.
The SAP system offers two primary methods for transferring data into SAP systems. From non-SAP systems or legacy system. These two methods are collectively called batch input or batch data communication.
1. SESSION METHOD
2. CALL TRANSACTION
3. DIRECT INPUT
First step for both the methods is to upload the data to internal table. From Internal Table, the data is transferred to database table by two ways i.e., Session method and Call transaction.
Session is intermediate step between internal table and database table. Data along with its action is stored in session i.e., data for screen fields, to which screen it is passed, the program name behind it, and how the next screen is processed.
When the program has finished generating the session, you can run the session to execute the SAP transactions in it. Unless session is processed, the data is not transferred to database table.
A technique similar to SESSION method, while batch input is a two-step procedure, Call Transaction does both steps online, one after the other. In this method, you call a transaction from your program.
SESSION METHOD
Data is not updated in database table unless Session is processed.
No sy-subrc is returned.
Error log is created for error records.
Updation in database table is always synchronous
CALL TRANSACTION
Immediate updation in database table.
Sy-subrc is returned.
Errors need to be handled explicitly
Updation in database table can be synchronous Or Asynchronous.

How to call a method of another class ?
Hello,
I�d like to know how to call a method of another class. I have to classes (class 1 and class 2), class 1 instantiates an object of class 2 and executes the rest of the method. Later, class 1 has to call a method of class 2, sending a message to do something in the object... Does anybody know how to do that ? Do I have to use interface ? Could you please help me ?
Thanks.

How do you call a method from another class without extending as a parent?
How do you call a method from another class without extending it as a parent? Is this possible?
Why don't you just create an instance of the class?
Car c = new Car();
c.drive("fast");The drive method is in the car class, but as long as the method is public, you can use it anywhere.
Is that what you were asking or am I totally misunderstanding your question?

both ShopBook.java and DataBean.java lies in the package shoppack.
in ShopBook i tried to instantiate the object to DataBean as
DataBean db = new DataBean();
it shows the compiler error, unable to resolve symbol DataBean.
